----------------------------------------
Summary: Error after updating attribute's data type of an Atlas
type
Key: ATLAS-1730
URL: https://issues.apache.org/jira/browse/ATLAS-1730
Project: Atlas
Issue Type: Bug
Components: atlas-core
Affects Versions: 0.8-incubating, 0.9-incubating
Reporter: Sharmadha Sainath
1.Created a type with one of its attributes' type as date and POSTed the type
definition to
{code}
/api/atlas/v2/types/typedefs
{code}
2. Tried to update the attribute data type to string , hence modified the JSON
(changed "date" to "string") and PUT the JSON to the same API which succeeded.
3. Tried to create an entity of the type and provided "val1" as value for the
string attribute (which was updated from date).
4. Entity creation failed with
{code}
java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.String
{code}
This could be a rare one but this scenario might cause issues when user
initially gave data type as "date" by mistake and wants to update it as
"string".
Also , since attribute delete is not allowed as part of type update , attribute
with "date" type can't be deleted and recreated with string.
